Abstract: The variable structure guidance law of extra atmospheric interception is studied. Inorder to eliminate the effects of outer and systematic perturbation and disturbance, a guidance law based on the variable structure control theory with a strong robustness is proposed. The coefficient matrix of the switching function is determined by the concept of zero control interception. The asymptotic law which guarantees the quality of transient process before reaching the switching surface is used in practice. The results of digital simulation and comparison with the proportional and optimal guidance laws are included.

Key words: extraatmo spheric interception, variable structure, guidance law
